'I'his invention relates to farm implements-k of the direct connected type and particularly to attaching brackets for connecting a cultivator oi' the type which is adapted to be swung across the front of the tractor incidental to movement of the steering mechanism.

The principal object of this invention is to provide an attaching bracket for the pendulum, swing type cultivator when attached to a tractor of the tricycle type that will support the cultivator within the confines of the forward end of the-tractor, so that visibility of the plant rows by the operator is enhanced.

It is another object of this invention to provide l5 a bracket for pendulum swing type cultivators, which may be -readily attached to or detached from the tractor, and to which the cultivator swinging arms may be easily attached when the tractor is moved intoV alignment therewith for Y attachment to the cultlvator.

In general, this invention resides in an attaching bracket assembly adapted for connecting an attachment to the usual attaching bracket plates carried by the tractor and 'comprisingtwo 5 vertical bracket support members which are braced to the tractor bolster and which are so spaced in front of the tractor as notvto lie generally within the view of the operator of the tractor; also, bracing means for fixing the upper ends of these vertical support members, and the support 'members-having means at their upper ends for attachingswingingarms, which support the cultivator.

The cultivator comprises, in general, a transverse pipe frame which carries straddle-row cultivator gang implements adapted to be supported vby the swinging arms when the same are attached to the present bracket support. The vtransverse supporting member is connected by 4o connecting links and levers to a vertical steering shaft and is swung to the right or left by the operator in response to vmovement of the steering wheel. A

For other objects and for a clearer understanding of the invention, reference may be had to the following description taken with the accompanying drawings, in which:

l Figure 1 is a side elevational view of a tractor ofthe tricycle type having one of its rear wheels removed and to which the cultivator is attached by means of an attaching bracket assembly of the present invention;

Figure 2 is a front elevational view of the tractor, cultivator, and also ofthe attaching bracket; Figure 3 is a side elevational View taken on the `Appnnmon.nine 19, 1937, sei-1am. 149,072

(ci. sav- 41) line 3-3 of Figure et assembly; and, Y Figure 4 is an elevational view taken on the fline 4-4 of Figure 2 of the yshifting lever mechanism on the steering shaft.

In Figures 1 and 2 there is shown a tractor of the tricycle type having a rear axle housing II and side sills I2 spaced at the forward end by a tractor bolster I3, through which a steering shaft I4 passes to the front wheel steering truck I5.- Connected to the upper ends of the steering shaft I4 by means of gearing is a steering rod I6 running rearwardly and longitudinally of the axis of the tractor to a point near the operators station I1, and having on the end thereof a steering wheel I8.

On the forward end of the tractor sills are secured the usual bracket plates I9 and I 9', having upper slots 2| and lower slots 22 adapted to receive attaching bolts of the bracket assembly to be presently described.

'I'he separable hang bracket assembly, in which the present invention resides, consists of two vertical, forwardly bent attaching bracket support members 23 and 23', each of which has in its lower end portion bolt clamps 24 and 25, which 2, showing in detail thetrack-f.rjV

are adapted to be disposed in the aforementioned slots 2| and'22 of the. tractor bracket plate for attachment oi' the same to the tractor. The upper bolt clamps are adapted to include a vertically extending brace 26 in rear of the vertical support members 23 and 23 and adapted to be attached to the same at a point near the upper end vfor the purpose of bracing the vertical support at that point. For further bracing of the vertical support members 23 and 23' there is a tie brace member 21 adapted to connect the upper ends of the vertical supports at the same point that the braces 26 connect with the supports, and tied to the tractor bolster I4 by means of a U-bolt 28. This provides adequate bracing for the bracket assembly when once it is attached to the tractor.

The upper ends of the vertical supports 23 `have a portion thereof turned down to provide an inverted U 29 adapted to receivethe ends of vertically extending swinging arms 3| and 3l and connecting pins 32 and 32' therefor, and at the lower end it is turned forwardly at 33, having a slot 34 for retaining the bolt 25 prior to swing- 50 ing the same up into the tractor bracket slot 22 when connecting thev bracket assembly to the tractor. It will be obvious that a quick attachment of the bracket assembly is to be effected in the bracket assembly of the present invention.

of the weight carried by the transverse bargthis l lconsistsgenerally of a main transversepipe bar 38', which extends across the front oftthetractor to 'pointsfremoyed vfrom'the Yand from the vertical supports 23 at- `tachedtothesills. 'Ihisbaris the main support" barfor outsidevcultivator gangs 86 andv 28 and 4 insidecultivator gangs 81 and 21'. andthe same is adapted to'be hung from the vertical supports I 28 and28'vby thejswingingarms 8l and 3l'- at e tached-fto'the by means voi' the pins rl2 and Y to engagethe transverse barby meansof their rearwardly turnedportionsl extending through sleeve members" :s and 39'., welded Vor secured tov the under surface of the transverse bar. In view L means of connecting theswinging'arms Il `and l;li`"'to the transverse support/.eliminates theA placing of `the downward strain ofthe swinging arms on a single cotter pin or thread connection that mighthave been used. Further.' the arrangement of theseswinging arms do'wnover the front ofthe transverse bar fpermits the trans' i verse bar tobe` located nearerto thew front end of the tractor, as isdesirable directly connected types ofimplemerlts.V

' The cultivatorgangsare'attached for'pivotal V movement .to they transverse support 36 by drag d beams 4l and '4P-"for the outside gangsand 42 vand 42' for the inside gangs to gang beam hangers 43' iixed tothe transverse support by hanger clamps'4`4. 'These gang beam hangers 42 `may' vbe set at any positionalong the transverse sup.

The tractor.` gangsniamg thus be raised out of engagement with the: ground Y and completelycarried by the tractor. v .n yThe. description thus far shows the cultivator1 and itsV transverse bar completely mounted ion' the tractor and adapted for raising and lowering or the eumvawrgangs.l The Vparticularmeans i for controlling the transverse movement of` the Y transverse bar with relation to movement'of the z steering lwheel will nowbedescribed.- i .Asbest` shown inFlgure 4, there is provided"a`1- fshift arm 88 ilxed to the steeringshaftfllgby vmeans of aspline 89 andadapted to swing theref` with.` i Journalerl to -the shaft I4 about the shift arm 8l isan axle spacerti having a projecting portion 92 with aslot '88 intheend thereoifA` collar 94 xed to the shaft I4 supports the-'shift .lever 68 and the axle spaceral on theshaft. t,

Between ithe shifting lever 88 yandthe $2 n of the axle spacer 9|,there isfslid-a shift latch having pivotedthereon a4 latch element I6 within a slot 81 and pivoted to a pinfiflxed ona; e depending bracket 69 and permitting rotation of the latch on the pin 9|. The rearend of the shifting latch member 95 has an -upstanding bolt IIII adapted to-it in the slot 93 of thefaxle spacer" f V8| and ilxed thereto byfmeans of a nut |02. i'he upper end of the latch element 96 has-a ,spring |03 attached thereto and connected withhthe" n upper endlef thefbon m to resiliency humane we` latch element 86 against the forward end of the driving engagement of the steering shaft with the latch mechanism 85.

. The outer end of the latch mechanism is connected to the transverse support member by means of a shifting` lever link |05 (Figure 2) that is attached to the ,shifting lever through an I-bolt |08 and to a projection v|01 on the transverse bar 35. It will now beseen that any movement of -the steering mechanism will cause a swingof the cultivator to the right or to the left, as may be desired bythe operator of the implement. 4

In order to disengage the connection of the steering mechanism with the cultivator supporting bar upon lifting the cultivator gangs out of the ground to a transport position, there is provided a throw-out rocker arm |08 supported on the transverse bar 35 by means o f a throw-out support bearing |09 and a bearing I on the projection |01 which is. detachable therefrom to permit removal of the throw-out rocker arm from the transverse supportV bearing |09. The throw-out rocker .arm |08 is placed in position by feeding it through the bearing support |09 and-then attaching the same in the bearing support on the `projection |01. The bar |08 has portions spaced from the bar to flt behind the latch 96 of the throw-out mechanism 95 and a slot ||2 of a throw-out bar I3 pivoted to one of the lift lever rocker arms 13 (Figure l) It should be understood that any movement of the lift lever mecha- `nlsm will cause the throw-out bar to operate the latch 96 to disengage the same from slot |04 of the shift lever arm 88, and that as long as the cultivator tools are in ground engaging position, the latch 96 will remain connected to the shift arm 88.

It should now be apparent from the above description and from the showing inthe drawings that there has been provided a bracket for the support of the cultivator of the pendulum swing type adapted to be Aoperated by the steering mechanism, that is of simple construction and within the confines of the front end of the tractor wherein the forward visibility of the operator is not impaired. Also, a construction has been provided which permits easy attachment or detachment' of the cultivator to and from the tractor. To detach the cultivator from the tractor, the cultivator gangs are first lowered to the ground. Front stand clamps ||4 are loosened to permit lowering of the front stands I5 to the ground where they are again clamped to provide for a iront end 'support of the cultivator. The offset arms I1, 48 and 48 are loosened fro-m the tool bars to permit rearward rotation of the cultivator tools and allow clearance forthe steering truck. Next, the cutter-pin 66 of the push pipe connection 6| is removed and the push pipe is lifted out of the holes 61 of the push pipe plate 68 and rested on some sort of convenient support means. The nut |06 of the bolt |0| is now loosened, thereby disconnecting the latch mechanism' 95 from the axle spacer. The swinging arm connections 32 and 32 on the vertical bracket supports are disconnected and the tractor may now be backed out of the cultivator apparatus. It will thus be apparent that, by carrying on these operations in the reverse manner, the apparatus may be accordingly attached to the tractor.

The attaching bracket of the present invention and push pipe plate 88 may be left on thetractor or readily detached, if they should interfere with the mounting or work ofsome other implement to be used. By leaving the bracket assembly attached to the tractor, one step in the operation of attaching pendulum type cultivators to the tractor is eliminated. The bracket is left intact and does not carry the swinging arms, since they remain on the cultivator apparatus.

It shan be understood-that the present invention herein described is obviously capable of cerltain modifications without departure from the spirit and-scope of the appended claims.
